초록

MIMO 시스템은 안테나 다이버시티와 공간 다중화의 적절한 조합에 따라 여러 가지 전송모드를 가질 수 있다. 이 논문에서는 비트 오류율에 관한 조건을 만족시키면서 전송용량을 최대화하는 전송모드를 찾고 특정 모드에 대해서는 각 안테나의 전송 기법을 최적화하는 방법을 제안한다. 모의실험을 통해 제안된 기법이 기존 기법에 비해서 전송용량을 향상시키는 것을 보인다.

MIMO transmission systems can have various transmission modes, which result from the various combinations of the antenna diversity with spatial multiplexing. In this paper, we find the optimal mode to maximize the capacity with the BER constraint and the optimal selection (diversity transmission or spatial multiplexing transmission) for transmission of each transmission antenna, if necessary. The computer simulation results show that the proposed scheme has more capacity than the conventional scheme.
